    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 ?`bi8 Ck  
    zePVB -@u  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: HQJ_:x Y  
    enableservice('AutomationServer', true) hO w  
    enableservice('AutomationServer') 8/F}vfKEN  
    UmUw>+A  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 2#1"(m{

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: mSF>~D1_  
    1. 在FRED脚本编辑界面找到参考. OC34@YUj[  
    2. 找到Matlab Automation Server Type Library AiKja>Fl<  
    3. 将名字改为MLAPP ^aYlu0Wm

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 }K':tX?

    现在将脚本代码公布如下,此脚本执行如下几个步骤: tIn dve  
    1. 创建Matlab服务器。 NbgK# ;  
    2. 移动探测面对于前一聚焦面的位置。 O{b<UP'85  
    3. 在探测面追迹光线 N3dS%F,_  
    4. 在探测面计算照度 nwuH:6~"  
    5. 使用PutWorkspaceData发送照度数据到Matlab cCx@VT`0  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $cjwY$6  
    7. 用Matlab画出照度数据 ;w>Dqem  
    8. 在Matlab计算照度平均值 WzG]9$v &
